Xbox One X will equally not be a giant factor when it comes to recovering Xbox One sales, it's a premium product. 20% of PS4 sales are the Pro, and that's a device that's 48% more expensive then the PS4, while the X is literally twice the price of the S. The market for expensive more powerful consoles isn't big enough to be anything more then a supplement.
Whilst accurate... One thing to keep in mind is that the base Playstation 4 was still selling stupidly well.
The Xbox One S isn't. So it wouldn't be hard to imagine for the Xbox One X to have a more favourable sales ratio... But it is unlikely to be a game changer due to overall higher costs anyway.
PC users enjoy differnt things than console users.... a game like CS-GO is pretty popular on the pc, but would it sell well on a console?
Its way to early to assume PUBG will get 10m on the xbox platform alone, or turn things around for xbox.
Counterstrike never sold well on console. Well. Not as well as PC. Being an eSport kept it selling on PC.
PUBG is getting allot of attention... If Microsoft can secure it as an exclusive... It might give them a slight push.
